I'm not sure I've followed what you're doing.

If you get as far as "todo.sh list p:" it will complete projects, and after
you type "todo.sh list @" it will complete contexts; the same for any
word after a "list" subcommand.

I note I don't complete projects or contexts in normal text, which is
potentially useful and easy to add.  In that case handling words in
quotes is a good idea since you've got a string of words in the same
argument before the bit you want to complete.  Possibly that covers what
you want.

I've attached the modified function so you don't need to get the
original out of the CVS archive (it has lines longer than 80 characters).

#compdef todo.sh

# See http://todotxt.com for todo.sh.
# Featurettes:
#  - "replace" will complete the original text for editing
#  - completing priorities will cycle through A to Z (even without
#    menu completion)
#  - list and listall will complete p:<project> and @<where> from
#    values in existing entries
#  - will complete after p: and @ if typed in message text
